7digital to drive the Galaxy S 4's Music Hub, ship on 100 million phones in 2013

If you've shopped at Samsung's Music Hub, there's a good chance that you've used 7digital's music services at some point: it's been involved in supplying songs for the past two generations of Galaxy flagships. That influence is carrying on to the Galaxy S 4, where 7digital will handle the Music Hub's storefront and purchased track streaming. While the deal doesn't represent a radical break for either side, it does give Samsung some odd bedfellows this time around -- 7digital is also operating music stores for BlackBerry 10 and Ubuntu One, and its apps have regularly surfaced on HTC devices and various Windows Phone models. Ultimately, 7digital expects its music shopping backbone to reside on more than 100 million smartphones before 2013 is over and done. That's no mean feat when the limelight often falls on music service rivals that insist on putting their names front and center, such as Amazon, Apple or Spotify.
